LEWIS CARLISLE MILES AND JOHN CARLISLE MILES, F BOISE,

VENDING MACHINE.

Application filed July 8,

To all whom it mag concern..-

Be it known that we, LEWIS CARLIsLE MILES and JOHN CARLISLE MILES, citizens of the United States, and residents of Boise,

in the county of Ada and State of Idaho,

have invented certain new and useful Improvements in Vending Machines, of which the following is a specification.

Our invention relates to improvements in vending machines and it consists in the constructions, combinations and mode of operation herein described and claimed.

An object of the invention is to provide a machine for vending perishable confections such as-Eskimo pies, ice-creams, and

combinations thereof, means being installed in the machine for keeping such confections in a salable state for a reasonable period of time.

A further object of the invention is to provide a machine for the purpose described 1 comprising a vending mechanism which is intended to remain in the possession of the retailer, a container of vendable articles which is to be furnished to .the retailer for attachment to the vending mechanism, and a cap to closethe container during transit between the place of supply and that of the retailer.

A further object of the invention is to provide a machine for vending frozen confections through the instrumentalities of -which the purchaser may Wait upon himself and thereby eliminate the intermediate handling which is-ordinarily required of the retailer. I a

A further object of the invention is to provide a machine for vending frozen confections, the shell ofwhich is so insulated (by vacuum spaces or otherwise) to such a degree of eflicency that the container as well as the entirely assembled machine, may be shipped long distances without danger of the contents spoiling. A further object of the invention is to provide a machine for vending not only frozen confections, asstated above, but also many other kinds of perishable articles which can be confined in package sizes.

Other objects and advantages reside in' the special construction and operation of various mechanical; parts as described in the following specification, reference'being had to the accompanying drawings, in which:

. insulate the contents against the passage of heat.

Upon arriving at the place of the retailer, v

' the cap 3 is removed and the vending mechanism 1 placed in its stead, being secured there by a coupling of any approved design.

The operation of the machine is such that the column of vendable articles4 (Fig. 4) is moved up into the vending mechanism step-by-step, this method of feeding being regarded'as preferable because thereby the warmest articles will always be served first,

, the coldest articles being those which must remainat the bottom and hence be served last.

A modification of the manner of'feedin'g would obviously be to feed the articles into the vending mechanism 1 by gravity (reversing the arrangement in Fig. 4) but, as just stated, the upward feedis preferable because bythis arrangement the natural tendency of cold air to settle at the bottom is more readily taken advantage of. The follow.- ing description is divided into three subj ects, representing the aforesaid major parts of the invention, taking first i The container 2, wh1ch comprises outer, intermediate and inner walls 5, 6 and 7,

which respectively define vacuum and ice spacesS and 9'as shown in the drawings.

"The space 8 is necessarily a complete enclosure from which the air is exhausted by any suitable means, in order to leave, a vacuum for the purpose of'insulating the vendable articles 4 against the absorption of heat from the outside. Although the vacuum space is doubtless the most efficient as an insulating medium, it may be stated that other insulating means, such as packings, etc., may be employed if desired. Both the vacuum and ice spaces arecarried beneath the bottom of the inner container 7 butthe use or non-use of thisparticular feature is optional. i I f An outlet 10 enables the draining of wa-' ter from the ice space 9, a plug 11 being used to close the opening. The purpose of the space 9 is to enable packing the container with ice at such time when it is doubtful that the articles 4 are sufiiciently cold to keep over a relatively long period of time. Under ordinary conditions, as when the articles 4 have a quick sale, the ice packing will be unnecessary because the articles are "put into the container in a chilled state and the vacuum space will act to keep them so for a reasonable time.

v screw.) with the gear 28.

Inside of the container 2 there is a squarethreaded elevating screw 12 which carries the platforms 13''14 through the medium of the elevating hub 15. Suitable bracing means 16 supports the platform on the hub. The part 13 of the platform is one-half the thickness of the article 4 higher than the part 14, this arrangement being necessary for the contemplated operation of the pushers 17 and 18 of the vending mechanism 1.

Screw threads 19 at the top of the container 2, enable securing the vending mechanism in place by means of a similarly threaded coupling collar. 20 which is peripherally serrated-to facilitate manipulation.-

This collar is swivelled on the vending mech anism at 21. The mode of connecting the vending mechanism and container is not necessaril confined to the use of a coupling col lar. pring clamps 22 (Fig. 18) may be used instead, and in this instance a pen-. 1

pheral rib 23 on the container 2 (in place of the threads) furnishes a place for the spring clamps to grip andso hold the two tion with a threaded opening 26 in the bearing. A screw may be inserted in this opening to enter the groove and thus provide a swivel mounting for the screw, but it will probably be desirable to omit the screw and merely depend on the' bearing 24 to hold the elevating screw 12 in place.

' The upper end of the elevating screw 12 extendsslightly beyond'the top edge of the container 2, thereby projecting a sufiicient distance into the vending mechanism 1 to effeet the engagement of the inion 27 (on the is gear is adapt,-

ed to be revolved in approximately quarter turns, and in doingso, turns the pinion 27 and elevating screw 12't0 raise the platform ,13, 14 a little at atime and so bringthe articles 4 into position to be discharged from the machine' v The cap 3 is .deep enoughvto enclose the extending part ,Of the elevating screw 12 when fitted in place. on. the container 2.

Little else can be said of the'cap 3 (Fig. 3) than that it too has a vacuum space 29 to correspond with the vacuum space 8 of the container, 'and threads 30 to engage the threads 19 of the container. When fitted in uum space around the vendable article.

The vending mechanism 1 is surrounded place for transit, the cap 3 completes a vac.-

by a vacuum space 31 only in so far as the.

pushers 17 and 18 and the directly .assos ciated mechanism is concerned, this arrangeo 17 is in the retracted position.

34 passes through a stuffing box 35 in the vacuum-spaced Wall and then through a chamber defined by a cover 36 containing the ratchet and coin devices. The crank 34 operates between back and front stops 37 and-38 (Fig. 8), and when the crank is pushed toward the stop 38 (assuming a coin to have been inserted) the gear 28 w1ll move a quarter-turn, partially rotate the pinion 27 and screw 12, slightly elevate the platform 13, 14 and-cause each of the pusherarms 39,40, and 41, 42. to turn a distance of 90 degrees, corresponding to the quarter turn of'the crank shaft 32 and of thegear 28.

The pusher arms are arranged in pairs and are so disposed on the crank shaft 32 that 'the individual arms are 90 degrees apart. The arms 39" and 40 operate the pusher 17 twice before the other set of arms has moved around into position to operate the pusher 18, whereupon the pusher 18 is By the time that the also operated twice. arms 41 and 42 have accomplished the double operationof the pusher 18, the arms 39 and will again have come into position 35 to operate the pusher 17 as stated before.

According to this mode of operation, the vendable articles are displaced from the to -of the four layers inthis order; :4 first, 4" second, 4 third and 4 last (Figs. 6 and 12).

Domes 43 and 44 make room for the passagejof the respective'pa-irs of arms. The pusher 17 is carried by a. pusher bar 45 (Fig. 13) which is mounted in a rectangular sleeve 46. This sleeve has a slot 47 on one side for 45 the passage of pins 48 and 49 with which the .arms 39 and, .40 cooperate in pushing the articles 4 and 4 ofl (Fig. 12).

A spring 50 tends to hold the pusher 17 in a retracted position against the end of 5 the sleeve 46. One end of this spring is fastened at 51 to the pusher bar 45', the other end being fastened at 52 to the sleeve 46. The adjacent side of the sleeve has a slotted opening 53 (Fig. 13) to enable reaching the pusher bar by the fastening 51. The sleeve is secured at 54 (Fig.15) in a rearward extension 55 of the vending mechanism casing this extension being ample ,enough to admit the rearward pin 49 when the pusher While the drawing shows a cover plate 56 closing the exposed end of the extension 55 and also shows the pusher bar 45 extendingthrough the cover plate, it would obvidoor 72 (Fig. 5).

ously be desirable to enclose the pusher bar so that no part of the mechanism be exposed. As the drawing is intended largely for the purpose of illustration, the showing made is deemed sufiicient. An arrangement identical with that described for the pusher 17 is made for the pusher 18, the bar 56' of which has pins 57 and 58 to be engaged by the arms 41 and 42-at the proper time; A spring 59, connected like the spring 50, serves to retract the pusher 18 when the second pin 58 has been disengaged by the arm 42 after the last article 4 has been pushed off. 5

A centering bearing 60 is intended to sta bilize the upper end of the elevator screw 12 when the whole machine is assembled. Each container of vendable articles must carry its own elevatorscrew 12 and pinion 27 because it would be impracticable and undesirable to require the'vendor to insert an elevator screw into-the hub 15 of the elevator platform each time that he finds it necessary to replace a container then in use under his Vending mechanism. As the depression 61 of the bearing 60 isshallow and fla'ring, it will be an easy'lnatter for the vendor to find the position for the upper end" of the elevator screw-when fitting the vending mechanism on the container.

The ratchet device, referred to above, consists of a ratchet wheel 62 fixed at 63 (Fig. 16) on the end of the crank shaft 32, I

necessary that the crank shaft 32 rotate in p one direction only and "the crank 34 move 32 to provide a recess 66 to receive the inner.

end of the extension 32 and form a supporting bearing therefor.

' A link 67 is pivotally connected at '68 to the upper end of the pawl arm 65 and at the other end is connected at 69 to an arm 70 at one end of a rod 71 which carries the trap This trap door constitutes the inner closure of a chute 73 into which the articles 4 are discharged by the two pushers. The door 72 opens into a recess 74 in the roof of the chute (Fig. 5).

U on moving the crank 34 rearwardly towar the front stop 38, the shaft 32 is correspondingly rotated by means of the pawl 64 and ratchet 62, this rotation ofthe shaft causing the operation of a pusher to discharge one of the articles, the same operation moving the link 67 toward the left to prevent .the entrance of dust, and in a measure aid in keeping warm air out. The

/ purchaser must raise the door 75 in order to secure the article which has been deposited in the chute 73.

A spring 76, connected between the link .67 and an adjacent wall of the casing (Figs( ward movement of the crank 34 is not possible unless a coin of the proper denomination be inserted into the coin mechanism, whereupon it becomes (for the time being) a part of that mechanism in displacing the pawl 78 (Fig. .9) whichwould otherwise prevent a full movement of the crank.

. The coin mechanism comprises a lever 79 with a dog 80 pivotally mounted at 81 on the angularly bent end 82. This dog is rigid on the movement of the crank 34 in one direction but capable of yielding on the return movement, this for the purpose of passing the auxiliary lever 83.

The horizontally angled portion 82 of. the coin lever 79'moves in the arcuate slot 84 of the coin trough 85 into which the coin 86 falls upon being inserted into the chute 87 The coin falls into position in front} of the lower end of the auxiliary lever 83 and thereupon moving the. crank- 34 rearwardly, the coin lever 79 pushes the auxiliary lever .83 (through dog 80) and the coin 86 toward the pawl 78, and since the coin Y precedes both 'levers,-the 'paWl is forced to rock on its pivotal mounting 88 into such a position (see dotted lines) that when it is engaged by the dog of the coin lever further movement of the latter will simply continue the-rocking of the pawl and let the coin lever 79 by.

- A spring 89 pulls the auxiliary lever 83 back against a stop 90 and, similarly, a

spring 91 pullsthe pawl 78 back against a" stop 92. 'One side of the chute 87 is open (as shown) to allow for the swingln ofthe auxiliary lever 83 and the upper en of the coin trough .85v is also opened so as toallow i for the operation of the dog '80 which, with the coin lever79 describes approximately a ninety degree are of acircle. I i i A coin receptacle 93 is located beneath the trough 85 to catch the coins as they fall.

This receptacle is hinged at 94 and is. fass tened by means of alock 95 and key. 96 (Fig. 6). Upon desiring to empty the coin receptacle, the vendor has only to undo the lock and swing it outwardly on its hinges whereupon the coins may be removed.

The operationmaybe' briefly reviewed to advantage. The purchaser inserts a coin of the proper denomination in the exposed '-portion 97 of the chute 87 (Figs. 8 and 9).

9) the pawl 78 is caused to rock into the dotted line position which is such a position as will allow the dog of the coin lever to pass. The crank 34 may be moved the entire 90 degrees or one-quarter circle required to displace one of the articles 4.

The movement of the crank 34 is .transmitted to the shaft 32 by means of the ratchet and pawl devices 62,64 described in connection with Fig. 16. Let the readerimagine the pusher'mechanian to be two steps behind the position shown in Fig. 5 so that the position in diagrammatic Fig. 12 is assumed. A prioraoperationof the crank 34 caused the pusher arm 41 to engage the pin 57, move the pusher bar 56 forwardly and cause the pusher 18 to shove the last article 4 over into the place of the article 4 and thereby cause the article 4 to fall into the chute 73 (Fig.-5).- This having been accomplished, the arm 41 disengages the pin 57 and the last pusher arm 42 comes into engagement with the pin 58.

The next operation of the crank 34 will cause the pusher arm 42 to move the pusher 18 therest of the w 'ay and displace the last article 4 in a manner precisely as before. the completion of this last movement brings .the respective pusher arms into the positions indicated in Fig. 5, at which time the pusher arm 39 is .in engagement with the pin 48 in readiness to actuatethe pusher 17 and displace the articles in the order previously described and indicated by the characters 4, 4, 4 and 4. The pusher arms 39, 40 first displace the uppermost articles from the layers on the adjacent side of the machine, whereupon the pusher arms 41, 42

follow by displacing the uppermost articles on the two layers on that side of the machine.v The action of the pairs of pusher Mention'hasbeen. made above of the. side 13 of the platform being one-half the thickness of thearticle 4higher than the side14.

This arrangement'is necessary to compensate, for the when of the pushe-rs 17and 18. The platform is' slightly elevated with each partial turn of the elevator screw 12, the degrees of elevation being approximately of the dimensions indicated by the dot and dash lines in Fig. 4, these being in-- dicated cab, 0, d, a and 6'.

Assuming the parts (including the articles 4) to be in the position in Fig. 5, a

- elevating the layers of articles 4 adistance movement of the crank 34: (as in performing the vending operation) will result in equalling that between the dot and dash lines so that the top of the highest layer- (left in Fig. 4) will approximately reach the line a, at which position the first article P will be pushed off. The following vending movement of the crank 34 will elevate the article 4 to the line b, the articles 4 and 4 in the meanwhile having been elevated first tothe position 0, then to the position d.

A subsequent vending operation crank 34 will elevate the layers of articles atthe right. (now the highest) to the line a, at which time the article 4 is pushed ofl, and the next operation of the crank will elevate the remaining article i to the line b, at which it too is pushed oil". The

articles in the layers at the left. are now highest and the former ,proceedingis repeated.

The action of the coin mechanism is doubtless clear. enoughbut the above description in connection with Fig. 9 may be supplemented by describing ,the action when no coin is inserted and an attempt be made to obtain one of the articles 4. It would require but a short turn of the crank 3i to move the auxiliary lever 83 against the adjacent heel of the pawl 78 by means of the dog 80 of the lever 7 9 which normally.

- engages in back of the auxiliary lever. At

such a time (dotted lines Fig. 9) the end of the auxiliary lever interposes an obstacle to the further movement of the coin lever 79, the pawl 78 being unable to move because the pressure is. applied tothe heelat a point slightly above the. pivot 88 and in the direction of the stop 92. However, the insertion of a coin and the subsequent pulling of the crank 34,'causes the displacement of the pawl so that the aforesaid heel moves downwardly in front of the dog 80 while the auxiliary lever 83 is moved aside out of range of the end of the coin lever, thus letting the coin lever pass and per:

mitting the operation of the machine. Instead of providing guides for the plat--' 'form 13, 14 in the compartment 7 of the container, thiscompartment is made of a rectangular shape (Figs. 6 and 7), there-c by serving the purpose of a guide both for the platform and for the layers of articles upon it. Figs. 1 and 2 illustrate the use -of a thermometer 98 to indicate the temperature of the vacuum space 8, and in actual practice some means will be provided for indicating the quantity of vendable articles remaining in the container.

Vhile the constructon and arrangement of the improvedvending'machme as herein described and claimed, is that of a generally of the to contain the vendable articles, a cover for the container to preserve the contents during. transit to the vendor, vending mechanism to replace the coverso that said articles may be vended, and means to secure the vending mechanism upon the container.
